Abstract
Kinetics of decomposition under the action of laser UV radiation is studied for alkynyl–phosphine complexes with bimetallic cores. It is shown that photodegradation is a zero order reaction, and the reaction rate depends on the substituents in the core of the complex. The sequence of decomposition processes is determined for the complexes after optical excitation. It is established that the rate of the ligand environment’s detachment is three times faster than that of the decomposition of the complexes’ cores. It is found that introducing halide ions into the structure of a cluster’s core increases the photochemical stability of the complexes.
